Hi, I have downloaded the developer version of source code by downloading a nightly Subversion snapshot tarball.And have installed the openmpi. Using
./configure --prefix=/net/hc293/chaitali/openmpi_dev (lots of output... without errors) make all install. (lots of output... without errors) then I have tried to run the example provided in this version of source code... the ring_c.c file... I first copied it to my home directory... /net/hc293/chaitali now when inside my home directory... i did set path=($path /net.hc293/chaitali/openmpi_dev/bin) set $LD_LIBRARY_PATH = ( /net/hc293/chaitali/dev_openmpi/lib ) mpicc -o chaitali_test ring_c.c (This gave no errors at all) mpirun --prefix /net/hc293/chaitali/openmpi_dev -np 3 --hostfile /net/hc293/chaitali/machinefile ./test_chaitali (This gave foll errors..)
